I used a Sawzall to cut the old lines roughly eight inches from the unions.

"Houston" we have a problem!!

The oil cooler was removed from the car with the union stubs attached.

The oil cooler union stubs required three hours delicate application of (propane torch) heat, PB Blaster, and torque to achieve separation.

FYI: The oil cooler is a folded path, tube and fin unit = gravity draining requires unreasonable time (days).
I prefer to use an air blow gun to gently force the oil out of the cooler, and zip tie a contractor trash bag to the output line.
Cleanup takes minutes.
